How does the dual servo drive system reduce the wear of mechanical parts of high-speed injection molding machines?-Ningbo Beilun Highsun Machinery Co., Ltd.

1. Basic principles and advantages of dual servo drive system
The dual servo drive control system uses two servo motors to control different moving parts in the high-speed injection molding machine, such as mold opening and closing, injection, mold closing and other key links. Compared with traditional hydraulic drive systems, servo motors can accurately adjust the speed and torque according to actual working conditions and respond dynamically, allowing the injection molding machine to maintain smooth and precise motion control during operation.

2. Working mechanism to reduce wear
Mechanical components in high-speed injection molding machines, such as gears, bearings, slides, etc., are usually affected by large pressure fluctuations and frequent start and stop processes when driven by traditional hydraulic systems. These factors aggravate the wear of components and lead to The reliability of the equipment is reduced. Especially when running for a long time, the "impact" working mode of the traditional hydraulic system often causes more serious wear and tear on the machine.

However, the dual servo drive control system significantly reduces wear through several mechanisms:
Precise torque and speed control: The servo motor can accurately control the output torque and speed according to the working requirements of the injection molding machine. When the load is small or the speed is low, the power output is automatically reduced. When the load is large, the system intelligently adjusts and increases the power output. Power output.

Smooth acceleration and deceleration: Servo motors are characterized by a high degree of control accuracy and can smoothly transition during acceleration and deceleration. Traditional hydraulic systems often experience large component vibrations due to oil pressure fluctuations or mechanical friction, resulting in additional wear. The servo motor can accurately control the acceleration and deceleration process of each step during operation, thereby avoiding severe friction and impact of mechanical parts and reducing wear and tear of parts.

Avoid excessive loading: In hydraulic systems, overloading is prone to occur due to large pressure fluctuations in the system, which in turn increases the wear and tear of machine components. The servo system uses closed-loop feedback control to enable the injection molding machine to dynamically adjust power according to actual load requirements, avoiding overload and reducing impact on key components.

3. Reduce maintenance costs caused by wear and tear
The direct benefit of reduced wear on mechanical components is a significant reduction in maintenance and parts replacement costs. In traditional hydraulic systems, due to high frequency of wear and damage, companies usually need to frequently replace key components such as seals, oil pipes, hydraulic pumps, etc., which not only increases maintenance costs but also affects production continuity.

The dual servo drive system can reduce friction and excessive load, significantly slowing down the wear of mechanical parts and thus extending the service life of the machine. For example, the wear of gears, bearings, sliders and other components in injection molding machines is almost negligible under long-term stable operation.

4. Improve equipment stability and production efficiency
The dual servo drive system enables high-speed injection molding machines to maintain higher stability in high-frequency production due to reduced wear and mechanical failure. The precise control of the system not only improves the reliability of the equipment, but also ensures that the injection molding machine can maintain consistent production quality under different working conditions, avoiding the increase in product defective rate due to equipment failure.

5. Synergy with other technologies
The dual servo drive system forms a good synergistic effect with other advanced technologies in high-speed injection molding machines, such as "proportional directional valve control" and "servo hydraulic system". The proportional directional valve can accurately control the flow and pressure of the hydraulic system. Combined with the precise control of the servo motor, the injection molding machine can maintain a higher response speed and stability during high-speed production, further reducing mechanical wear.
